Abstract (2. Language): 
Introduction: In scapula, the acromion process projects forwards almost at right angles from the lateral end of the spine. The coracoacromian ligament spans between tip of acromian and coracoid process thus it forms coraco-acromial arch. The space below the arch gives passage to the tendons of muscles forming musculo- rotator cuff. As morphometry of the acromion process of the scapula is an important factor implicated in impingement syndrome of the shoulder joint. Methodology: Present study carried out on the 129 dry scapulas of unknown age and sex, 67 were from the right side, and 62 were from the left. Measurements were taken using a sliding vernier calliper and recorded in millimeters Result: The mean values of scapular height and width were observed 145.1 mm and 105.5 mm in total number of scapulae respectively. The mean values of acromian length, acromian width and thickness were observed as 46.1 mm, 23.2 mm and 6.60 mm respectively. The distance taken from the Tip of Acromian process to the Tip of coracoid process was found 37.5 mm in total sample. The three types of acromion were observed as type-I flat was seen in 22.5%, type II curved in 38.8% and type III hooked in 38.8% respectively. Conclusion: Knowledge of the morphometeric values of scapula and acromian process is important for clinicians in understanding and curing shoulder joint aliments.
